Of the two, it would have to be the 29 for me. A friend has a 21, not a 20, which I've tried to shoot a bit. My stubby fingers won't wrap far enough around the grip to get a good one-handed hold. The 29 isn't good but it is less bad. 1911s suit my hands a lot better. I like 10mm but I prefer it in a revolver.
